R-Ras promotes cell adhesion and activation of integrins through a process that is yet unknown. We show here that active R-Ras (38V) promotes the formation of focal adhesions and a spread cell shape. By contrast, the dominant-negative mutant of R-Ras (43N) reduces the number of focal adhesions, leading to the formation of refractile cells. In adherent cells wild-type R-Ras, activated (38V) R-Ra...

background: domestic and industrial wastewaters are mostly treated by biological process such as activated sludge, aerobic pond, and anaerobic treatment. this study focuses on characterizing the quality of sewage sludge in the sultanate of oman chosen from three industrial sewage treatment plants (stps): rusayl industrial estate (rsl.ie); sohar industrial estate (sie); and raysut industrial est...

The use of reclaimed asphalt pavement (RAP) and/or recycled shingles (RAS) in the mixtures is a common practice U.S.A. However, there controversy to date on how RAP/RAS interact with virgin binders (VABs) mixtures. For containing RAP/RAS, aged RAP and air-blown RAS alter performances extracted (EABs). Thus, rheological properties EABs from these require more investigation. focus this paper was ...

The recirculating aquaculture system (RAS) is a cultivation that minimizes water changes and can optimize high stocking densities (SD). purpose of this study was to determine the effect nursery culture in density with RAS on survival rate (SR), specific growth (SGR), relative length (LR), weight gain (WG), (LG)and feed utility efficiency (FUE) juvenile catfish. used completely randomized design...

The role of three major Ras downstream effector pathways in the induction of mammary cancer was studied using an in situ mammary ductal gene delivery model. Replication-defective retroviral vectors were used to infect endogenous rat mammary epithelial cells with three individual Ras effector loop mutants, each of which transduces its signal through a different Ras effector pathway (Raf, PI3K or...

E-RAS is a member of the RAS family specifically expressed in embryonic stem cells, gastric tumors, and hepatic stellate cells. Unlike classical RAS isoforms (H-, N-, and K-RAS4B), E-RAS has, in addition to striking and remarkable sequence deviations, an extended 38-amino acid-long unique N-terminal region with still unknown functions. We investigated the molecular mechanism of E-RAS regulation...

Despite the fact that there are wastewater treatment plants (WWTPs) currently operational across Iran and great advances have been made in this area, there are still problems in the design, construction, and operation of WWTPs with large nonlinear systems, varying flow rates, and pollution charges. The objective of this study was to investigate the effect of operating parameters including the r...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
